Comes up in: AI system design, AI engineering, Take-home
This concept is being written. It gets the full five steps — explanation, predict, interview angle, practice with tests, and review cards. Here is exactly what it will cover, so you can study it elsewhere in the meantime.
What it covers
- API layer (Workers/FastAPI/Next route)
- streaming endpoints
- auth
- queues for long jobs
- storage of conversations
- provider abstraction and fallbacks
- gateways (e.g. Cloudflare AI Gateway)
Words you will know
What you will practise

Interview questions this answers

- How do you handle a provider outage?
- How would you roll out a prompt change safely?
